4-40 x 1/16 Alloy Steel Cup Point Socket Set Screw is commonly specified where a component must be secured from within a tapped hole rather than with an external screw head.
Applications often include shaft collars, hubs, and machine controls, where a headless fastener must hold a component without external head clearance. The internal hex recess gives the installer controlled drive engagement while keeping the fastener profile inside the tapped component.
The verified dimensions below help engineering and purchasing teams compare the screw to the application before ordering. Always confirm that the cup point contact is acceptable for the mating component and service conditions. The point geometry is intended for applications where localized contact is part of the retaining method, not for assemblies that require a nonmarking tip. Cold Headers helps match set screw thread, length, point style, and socket drive details for industrial purchasing and repair work.
